The 13 should be 31... then
1+1+1=3
1+1+3=5
1+3+5=9...
The next number in the sequence is 27.
17?
These are all prime numbers. The next one is 17
33
17
13
If you eliminate the first number, the rest are prime and the next one would be 29.
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
The pattern alternates between adding 11 and adding 2. Starting with 11, we add 11 to get 22, then add 2 to get 13, and continue this pattern. Following this sequence, after 17, we add 11, resulting in 28. Therefore, the next number is 28.
The next number in the sequence is 27.
8
17
-13
The pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.
17 cause it is the next prime number
minus 1, minus 2, minus 3, minus 4, minus 5... The next number is 6.
Actually the next number in the sequence is 17 A 19 , 23 , 29 , 31 ,.......... Prim number
